you dont need a skimmer for the 10 gallon, even with the proposed bio load...just feed on the light side and be diligent with water changes...frankly any of those skimmer would look silly on a ten gallon, and might not even physically function. The seaclone is bad, the skilter is too. Redsea I have heard mixed things about, and the coralife is good once you get it fine tuned.
